Subject: RE: [PATCH 0/8] Input: support for latest Lenovo thinkpads (series 80)
Date: Tue, 10 Apr 2018 13:45:33 +0800 [thread overview]
Message-ID: <firstname.lastname@example.org> (raw)
Thanks so much for your patch.
I have tested them for Elan Gen5/Gen6(new) touchpad with SMbus/PS2.
It works fine in my thinkpad so far but I find an issue today after lid-close/open.
I am not sure if you can see it in T480S , I "guess" it may be relative to i2c_i801.
The lid-close will enter deep sleep and cut touchpad power.
I can see the resume flow after lid-open and SMbus-initial try to request hello package but fail.
Strangely, I can't see any SMbus host signal on LA scope after power-on.
I can't switch to SMbus after rmmod/modprobe psmouse because error happen in elantech_create_smbus.
It will be recovered only if I rmmod/modprobe i2c_i801 first.
Do you have any idea about it?

thanks for the quick review.
I worked closely with KT for this series. He helped me a lot for the tiny firmware changes that were required. However, quoting his email from Tuesday:
"There will be a spring vacation in Taiwan from tomorrow." I guess we won't hear from him until the end of next week as we always have a backlog of urgent things to do after holidays...
